I recently was fortunate enough to acquire a Two Rock Jet 22. I wanted a footswitch that was smaller to fit on my pedalboard. Here’s the schematic I worked out and a shot of it working with the amp and how much smaller than the actual switch it is. On the Jet it switches boost and channel but may work with other Two Rocks that have a two button switch to switch boost and reverb.
So why all the 4007 diodes???
Not exactly sure, that’s just what they have in it. I think it ensures I certain voltage drop for the switch, but why they couldn’t have done it with just an LED and resistor like everyone else, I don’t know.
